* LSCM live transform is finally here!

This is a combined effort from Jens, Ton who finished the code here on my machine, and myself putting in the little menu toggle and committing :).

Turn it on and off in the UV/Image window menu UVs -> LSCM Live Transform. It recalculates the LSCM within the transform loop when you're transforming pinned vertices, so it gives realtime feedback - a real time saver! Note: this is much more powerful than proportional edit, since it's properly calculating LSCM using the correct edge angles, etc.

I recorded a quicky demo video here: http://orange.blender.org/wp-content/themes/orange/images/media/lscm_live.mov (quicktime animation codec)
